BACKGROUND To evaluate the risk factor associated with total or subtotal meniscectomy for respective medial and lateral meniscus injury. METHODS The data of all the meniscus injured patients undergoing arthroscopy in our institute between January 15th, 2000 and December 31st, 2008 was collected and 6034 patients with 7241 injured menisci met the inclusion criteria. The mean patient age was 33...

PURPOSE To investigate the patterns of medial meniscus (MM) tears in patients with varus knee osteoarthritis who underwent total knee arthroplasty and analyze the factors that could affect MM tears. MATERIALS AND METHODS The patients (365 knees, 268 patients) were classified into three groups; group I with MM posterior horn (PH) tear only; group II with MM root tear only; and group III with M...

Various shapes of congenital abnormalities of the meniscus have been reported. Among them, the double-layered meniscus is rare. This article describes a 22-year-old man with a double-layered lateral meniscus who reported right knee pain with no history of trauma. The double-layered lateral meniscus included both the upper and lower meniscus. The anterior and posterior edge of the upper meniscus...

PURPOSE To measure the lower tear meniscus dynamics with Fourier domain-optical coherence tomography (FD-OCT) in keratoconus patients without dry eye findings to evaluate the effects of the corneal ectasia on lower tear meniscus parameters, and to determine the most affected meniscus variable from the corneal ectasia in keratoconus. METHODS Prospective, clinical study. Forty-one eyes of 25 ke...

Twenty-two patients with cysts of the lateral meniscus have been treated by operation. A modified operative procedure is described whereby the meniscus is inspected for a concomitant tear. A tear of the meniscus was found in ten patients and these were treated by meniscectomy. The remaining twelve cases were treated by excision of the cyst only. The rehabilitation period was considerably less i...

introduction a discoid medial meniscus is a rare pathology of the knee joint, and is even rarer when it presents bilaterally with clinical symptoms. case presentation we present the case of a 38-year-old female with symptomatic bilateral discoid medial meniscus. magnetic resonance imaging (mri) showed complete discoid meniscus in one knee and incomplete, on the other side. the mri findings were...

Preservation of the meniscus has been shown to influence the progression of degenerative changes of the knee. As more meniscus is preserved, the propensity for development of osteoarthritis is lessened. Surgical treatment of a torn discoid meniscus has typically been a subtotal meniscectomy or partial meniscectomy. Similar to tears of a normal meniscus, partial meniscectomy compared with subtot...

Purpose. To compare the effect of airflow exposure on the tear meniscus and blink frequency in normal and evaporative dry eye subjects. Methods. In 9 normal subjects and 9 short tear breakup time (SBUT) dry eye subjects, lower tear meniscus height (TMH) and area (TMA) and blink frequency were measured with anterior segment optical coherence tomography (OCT) before and after 5 minutes of airflow...
